Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

POSIX concurrency control

In this section, we are going to have a look at possible control mechanisms that are offered by the pthread library. Semaphores, mutexes, and condition variables alongside different types of locks are used in various combinations to bring determinism to multithreaded programs. First, we start with POSIX mutexes.

POSIX mutexes

The mutexes introduced in the pthread library can be used to synchronize both processes and threads. In this section, we are going to use them in a multithreaded C program in order to synchronize a number of threads.

As a reminder, a mutex is a semaphore that only allows one thread at a time to enter the critical section. Generally, a semaphore has the potential to let more than one thread enter its critical section.

Note:

Mutexes are also called binary semaphores because they are semaphores that accept only two states.

We start this section by resolving the data race issue observed as part...
